Description of the plant:
Ulster Blue Dwarf is a compact variety of speedwell. It has fascinating spikes of deep violet to indigo blue flowers on 20-30 cm tall stems. The spikes remain beautiful for a long time without fading leaving the tips green. In humus-rich soil it is well-branched, and if regularly dead-headed it keeps on flowering until late summer. Leaves are broadly lanceolate, serrated at margins, deep green. Speedwell will grow in any moist but well-drained, reasonably fertile soil, preferably in full sun but partial shade will do no harm. Hardy to about -34°C (USDA zone 4), and will grow well in a container, too, where the soil should never dry out.
